GeroWallet Opens Its Browser Wallet Code to Public Review

GeroWallet has made the source code for its browser extension publicly available on GitHub, opening a substantial part of its technical architecture to external review.

The published code covers wallet management, security functions, transaction signing, staking, CIP-1694 governance, decentralized application connectivity and the browser interface.

As a non-custodial wallet, GeroWallet allows users to manage Cardano assets, stake ADA, delegate to DReps, interact with dApps and access DeFi functionality while retaining control of their private keys. Its public codebase also includes support for Midnight and Apex Fusion.

GeroWallet Opens Security-Critical Wallet Components

The repository exposes some of the most security-sensitive components of a non-custodial wallet.

GeroWallet’s documentation covers key derivation, encrypted key storage, password and PassKey handling, transaction construction and signing, along with Ledger, Trezor and Keystone hardware wallet integrations.

Private keys are isolated within the extension’s background service worker rather than exposed to the user interface. Developers can now inspect how those protections are implemented and how transactions move through the wallet before signing.

Cardano-specific functionality is also publicly visible, including staking, CIP-1694 governance, native assets, NFTs and the CIP-30 dApp connector.

The repository is structured for participation as well as review. Developers can fork the code, build the extension locally, make modifications and submit pull requests under GeroWallet’s current source-available non-commercial terms.

Cardano Remains Central to GeroWallet’s Multi-Chain Expansion

GeroWallet has expanded beyond its original Cardano focus, but Cardano remains deeply represented throughout the public codebase.

Its Cardano functionality includes staking, DRep delegation, governance participation, native asset management, NFT support and connectivity with decentralized applications. The wallet also integrates DeFi features, including swap routing across Cardano decentralized exchanges.

Blockchain data, price information, DeFi routing and real-time updates are handled through Gero’s separate Nexus data layer, while the browser extension contains the user-facing wallet and signing environment.

Midnight support includes shielded transaction functionality and NIGHT and DUST integration, while Apex Fusion support covers its Prime and Vector chains. Bitcoin remains part of GeroWallet’s roadmap rather than a currently available feature in the released wallet.

The public repository therefore provides a clearer technical view of how GeroWallet is expanding across multiple networks while retaining its Cardano-native wallet functions.

Catalyst Funding Moves Into a Public Development Phase

The release follows GeroWallet’s Fund 13 Project Catalyst proposal to move development toward a more open and community-accessible model.

The proposal received 50,000 ADA for codebase preparation, public release, documentation and a contribution process for external developers. Public Catalyst records currently show the project progressing through its planned milestones, with the first of three completed.

The GitHub repository now includes development instructions, an architecture overview, issue tracking and a defined workflow for submitting changes. Developers can also build the wallet locally and use Cardano Preprod for testing without interacting with real funds.

GeroWallet has documented one current limitation: reproducible builds have not yet been implemented, so locally compiled versions are not expected to match the Chrome Web Store release byte for byte.

With the browser wallet code now publicly accessible, Cardano developers can inspect the implementation directly, test their own builds and contribute changes through GeroWallet’s public development workflow.
